Apparatus for controlling engine of vehicle and method thereof

摘要

The present disclosure provides an apparatus for controlling an engine of a vehicle and a method thereof, and more particularly, provides an apparatus for controlling an engine of a vehicle and a method thereof capable of preventing damage on catalyst occurring upon controlling engine torque by controlling the engine torque based on an accumulated time of a torque decrease request from an ESC system or a TCS while monitoring temperature of the catalyst.

主权项

1. An apparatus for controlling an engine of a vehicle, the apparatus comprising:
a temperature sensor configured to sense a temperature of catalyst; a receiver configured to continuously receive a torque decrease request; and an engine controller configured to control the engine to retard an ignition timing as the torque decrease request is received through the receiver and control the engine to decrease engine torque by advancing the retarded ignition timing and adjusting an amount of air and an amount of fuel when the temperature of the catalyst exceeds a threshold temperature and an accumulation time of the torque decrease request exceeds a threshold time.
